In order to get the best mode, H.264 computes the cost of every mode for each block by RDO (rate distortion optimization) technique, but it increases a high computational complexity .This paper combines Pan's fast algorithm and an efficient fast mode decision for intra prediction is proposed. First, the intra prediction's types are decided by whether a block is smooth. Second, the Pan's fast algorithm...
In order to achieve the high compression efficiency, H.264/AVC adopts rate-distortion optimization ( RDO ) technology with full mode search in intra prediction. The computational complexity is so high that it isn't fit for real time encoding and hardware design. So we proposed a fast and efficient intra prediction algorithm. We choose intra luma 4times4 or intra luma 16times16 based on smooth degree...
As the newest video coding standard, H.264/AVC uses the rate distortion optimization(RDO) method to select the optimal coding mode after the calculation of all the possible modes. The computational complexity is increased drastically, so it isn't fit for real time encoding and hardware design. In this paper, we propose a fast intra mode decision algorithm based on texture feature for H.264/AVC. First...
